1 Claim. 1

This invention relates to a sucker rod elevator designed for elevating asucker rod and holding the sucker rod elevated while undergoing rep-airor while the sucker rod sections are being removed or connected.

An important object of the invention is to provide an elevator of thischaracter which comprises a member having a slot which is so positionedover a sucker rod adjacent to a sucker rod section coupling, that it maybe readily forced under the sucker rod coupling and when swung upwardly,will move to a vertical or elevating position wherein the elevator issecurely held on the sucker rod with which it is used.

With the foregoing and. other objects in view which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts hereinafter more fully describedand pointed out in the claim, it being understood that changes may bemade in the construction and arrangement of parts without departing fromthe spirit of the invention as claimed.

Referring to the drawing Figure 1 is a perspective view illustrating asucker rod elevator constructed in accordance with the invention, aspositioned under the coupling between sucker rod sections, prior tomoving the elevator to its operative position.

Fig. 2 is a perspective view illustrating the elevator as swung upwardlyto its operative position and in clamped relation with respect to thesucker rod being elevated.

Fig. 3 is an enlarged sectional view illustrating the position of theelevating tool with respect to the sucker rod.

Referring to the drawing in detail, the reference character 5 indicateswell tubing in which the sectional sucker rod 6 operates, the sectionsof the sucker rod being connected by means of the coupling 7.

The elevator comprises a heavy bar 8 of circular cross-section, one endof the bar being substantially square in cross-section, and extendedlaterally as at 9, providing a lift, the outer surface of the bar wherethe laterally extended end merges into the bar, being rounded as at l6providing a cam surface for contact with the upper end of the welltubing when the bar 8 is being moved to its vertical or liftingposition.

The laterally extended lift portion 9 is extended at right angles, toprovide a horizontal supporting surface, as shown by Fig. 2 of thedrawing, when the elevator is positioned on the sucker rod for liftingthe sucker rod.

A slot I0 extends from a point along the bar 8, into the laterallyextended portion 9, as clearly shown by Fig. 1 of the drawing, so thatthe device may be positioned over the sucker rod to be lifted, theelevator being positioned with the open end of the slot indicated at l Iplaced next to the sucker rod under the coupling 1, as shown by Fig. 1.With the elevator in this position, the outer end of the elevator isswung upwardly to a vertical position, the right angled or laterallyextended portion 9 moving to a horizontal position directly under thecoupling 7, where the weight of the sucker rod being elevated, isdirected to the laterally extended portion 9, the operative or elevatingposition of the elevator being shown by Fig. 2 of the drawing.

A yoke 53 is swiveled on one end of the bar 8 and affords means wherebya hook such as indicated at It and carried at one end or" a cable, maybe connected with the elevator, the cable forming a part of hoistingmachinery not shown, for elevating or hoisting the sucker rod undertreatment.

A right angled lug I5 is formed at one side of the slot it, the lugproviding a stop which may be positioned against the well tubing to holdthe device against slipping, as it is being worked under the coupling ofthe sucker rod to be lifted.

From the foregoing it will be seen that due to the construction shownand described, I have provided a sucker rod elevating device which maybe readily and easiiy positioned under a coupling used in couplingsections of a sucker rod together, the elevator being moved to avertical position moving the laterally extended member 9 formed in oneend of the main bar of the lifter, directly under the coupling, forlifting the sucker rod when the hook of the hoisting machinery notshown, is hooked into the yoke 13 at one end of the main bar of theelevator.

Having thus described the invention, what is claimed is:

A lifting device of the class described, comprising a bar, a portion ofone end of the bar being extended rearwardly in parallel spaced relationto the main portion of the bar, providing an open-ended slot, the entryinto the open-ended slot being along a line parallel to the axis of themain portion of the bar, a portion of the end of the bar having theopen-ended slot, extending at right angles to the main portion of thebar providing a lift portion, and the extremity of the rearwardlyextended end of the bar being disposed at right angles to the main barin a direction opposite to the lift portion, providing a stop.
